Between the normal hairs are many black tactile hairs.

However, manatees are unique since these tactile hairs are located over the whole post-cranial body in addition to the face.

Relative to other monkeys, they show some apparently primitive features: they have claws rather than nails, and tactile hairs on their wrists.

The large pincers are studded with highly sensitive tactile hairs, and the moment an insect touches these, they use their chelae (pincers) to catch the prey.

Technically called vibrissae, whiskers or tactile hairs are clustered in three major groups on the sides of the cheeks, above the eyes and farther back on the cheeks.

These specialized tactile hairs form the whiskers of the upper lips, and are also found on the cheeks and the chin, over the eyes and on the wrists of the forelegs.
